NAME

The RxD (RDM over DGRAM) Utility Provider

OVERVIEW

The RxD provider is a utility provider that supports RDM endpoints emulated over a base DGRAM provider.

SUPPORTED FEATURES

The RxD provider currently supports FI_MSG, FI_TAGGED and FI_RMA capabilities. It requires the base DGRAM provider to support FI_MSG capabilities.

Endpoint types : The provider supports only endpoint type FI_EP_RDM.

Endpoint capabilities : The following data transfer interface is supported: fi_msg, fi_tagged and fi_rma.

Modes : The provider does not require the use of any mode bits.

Progress : The RxD provider supports both FI_PROGRESS_AUTO and FI_PROGRESS_MANUAL, with a default set to auto. However, receive side data buffers are not modified outside of completion processing routines.

LIMITATIONS

The RxD provider has hard-coded maximums for supported queue sizes and data transfers. Some of these limits are set based on the selected base DGRAM provider.

No support for multi-recv.

No support for counters.

The RxD provider is still under development and is not extensively tested.

RUNTIME PARAMETERS

No runtime parameters are currently defined.
